7.5 pounds of Swiss cheese, WOW
In this case, we cannot simply take the average speed by
adding the two speeds and divide by two.
What we have to do is to calculate the time required
going to school and the return trip home.
We know that to calculate time, we use the formula:
t = d / v
where,
d = distance = 4.8 km = 4800 m
v = velocity
Let us say that the variables related to the trip going
to school is associated with 1, and the return trip home is 2. So,
t1 = 4800 m / (22.6 m / s)
t1 = 212.39 s
t2 = 4800 / (16.8 m / s)
t2 = 285.71 s
total time, t = t1 + t2
t = 498.1 s
Therefore the total average velocity is:
= (4800 m + 4800 m) / 498.1 s
= 19.27 m / s = 19.3 m / s
Answer:
19.3 m/s
Answer:
y = -8
Step-by-step explanation:
There is no x-variable as that would make the line tilt.
Hope this helps! Have a nice day!
Your answer will be x • 4³ = 64x
When simplifying powers, the rule is that if you’re dividing two powers with the same base (in this case the base is 4), you need to subtract the powers. For example, 3³ ÷ 3² = 3 (which is 3^1).
Using this rule, we can see that 4^8 ÷ 4^5 = 4^(8-5) = 4³.
The x is on top of the fraction and we’re not dividing by an x, so it doesn’t change. Therefore your final answer is 64x.
I hope this helps!
